%description
Implements a semi-supervised learning framework for finite mixture models
under a mixed-missingness mechanism. The approach models both missing
completely at random (MCAR) and entropy-based missing at random (MAR)
processes using a logistic–entropy formulation. Estimation is carried out
via an Expectation–-Conditional Maximisation (ECM) algorithm with robust
initialisation routines for stable convergence. The methodology relates to
the statistical perspective and informative missingness behaviour
discussed in Ahfock and McLachlan (2020) <doi:10.1007/s11222-020-09971-5>
and Ahfock and McLachlan (2023) <doi:10.1016/j.ecosta.2022.03.007>. The
package provides functions for data simulation, model estimation,
prediction, and theoretical Bayes error evaluation for analysing partially
labelled data under a mixed-missingness mechanism.
